You can set up a domain name that you own to point to another domain name. This is known as "parking" a domain.
The Parked Domain Maintenance menu allows you to add and remove parked domains to your account. A parked domain allows you to reach your domain when entering the name of the parked domain into a browser. Any current domains that are parked will be listed under Current Parked Domains. For example, if domain2.com is parked on domain.com, going to http://www.domain2.com in a browser will bring up domain.com.
